I tweaked it to run un linux. But I cannot access the addresses for the registers of the SPI controller. I tried remapping the physical addresses to virtual addresses that my program could use, but they are all 0's. it seems like my mapping is not correct.

What linux are you running? You need a device driver in linux for your device.

I am using Debian 5.0.2-1 and run on atmel 6263 on a cogent computers csb737. I use spi for external 24 bit sigma delta adc.

The linux is configured for that board.
